ANIMAL-SH EARS.

SPECIFICATION forming part of Iietters Patent No. 466,860, dated January12, 1892..

Application filed October 13, 1890- Serial No. 368,041. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES BURGON, sheep-shears manufacturer, a subjectof the Queen of Great Britain, residing at Malin Bridge, near Shefiield,England, have invented certain new and useful Improvements in lllachinesfor Shearing or Clipping Sheep or other Animals, of which the followingis a specification.

My invention relates to simplifying and making more eflicient theworking parts of machines for shearing or clipping sheep or otheranimals, my present improvements principally consisting in applying therequired pressure to the top and bottom cutters of such machines.

I attain the object of my invention by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a plan or top view of myimproved machine complete, excepting that its case or covering isremoved. Fig. 1 is a 1ongitudinal central sectional view of the same.Fig. 2 comprises and shows a side view anda back view of the frame ofthe machine and the recess or slot with the base-plate fitted in. Fig. 3is an end View of the base-plate. Fig. 4': comprises and shows a sideviewof the crankpin and the slide-block. Fig. 5 is a plan or top view ofthe case or covering of the machine. Fig. 6 is a side view of thescrew-pin, and Fig. 7 is a plan or top view of the rockerbar of myimproved machine.

Similar letters refer to similar parts throughout the several figures onthe drawings.

In carrying out my invention in practice I recess the frame a of mysheep-shearing machine to the necessary depth and shape, as shown at b,Fig 2, on the accompanying drawings. The recess I make, preferably, of aT shape, or it can be made of a D shape or of other convenient shape. Inthe recess I fix a metal base-plate c, correspondingly shaped and somade as to work like a hinge or to work on the centers d cl. It issupported on or at the sides of the base-plate by the frame a and eitherby the centers cl or by pivots carried-in the frame side. Having thusfitted the base-plate, I place arocker-bar e 011 it, which bar has atipping or rocking and 0scillating motion imparted to it, as hereinafterdescribed. The tipping or rocking motion I obtain by providing andfixing a screw fora cam or wedge 0r lever or other equivalent device, soas to raise or lower the base-plate at the opposite end, Where it ishinged. To obtain the necessary oscillating motion I pass a screw-pin 9through the rocker-bar e at or near its center, one end of the pin beingmade with a screw-thread on it. I then screw the pin into theoscillating base-plate c and so form a perfect joint for the rocker-barbetween the head of the pin and the oscillating base-plate. At the endof the rocker-bar e farthest from the cutters of the machine I fix asuitable crank-pin h, with a slide-block 'i, (or a ball arrangement maybe used, if desired,) which, when in action, will give the requiredoscillating motion to the frontend of the rockenbar e, to which bar thetop cutter is attached by means of screws or a pin or pins.

At the rear end of the spindle or drivingshaft of my shearing orclipping machine three or more (or less) universal joints j withballcouplings are attached, and they are externally protected andcovered by a coiled wire 7c, combined with two (or more) nuts Z Z forattaching to or detaching from the cutting mechanism and the flexibledriving-core of the machine. They are incased with leather or othersuitable covering.

By means of this appliance the operator is enabled to use the shearingor clipping machine in any desired position or direction.

A conveniently-sized metal case or cover m is provided for protectingthe working parts of the machine, which case or cover is attached to orsecured on the apparatus by screws n or by a spring-latch or by otherequivalent and suitable attaching device.

Having thus fully described my invention, I wish it to be understoodthat I do not claim. separately either the comb or the cutters or therocker-bar or the crank-pin or the slideblock used in this shearing orclipping machine; but

What I do claim as my invention, and dc sire to secure by LettersPatent, is-

1. In a sheep shearing or clipping machine, the combination, with frameat, having T- shaped recess, as described, of the oscillating base-plate0, supported by the frame, centers d cl, projecting into said recess andon which said base-plate works, a rocker-bar e, mounted on thebase-plate, and means for imparting both a rocking and oscillatingmotion thereto, substantially as set forth.

2. In a sheep shearing or clipping machine, the combination, with theframe a, recessed as described, of the oscillating base-plate 0,supported by the frame, centerscl d, on which said base-plate works, arocker-bar e, mounted on the base-plate, and means, such as a screw f,for imparting a rocking motion thereto, a crank-pin h, a slide-block i,a metal case or cover an, adapted tofit over and protect the workingparts of the top portion of the machine, and screws 72 a for securingsaid case or cover to the apparatus, substantially as set forth.

3. In ash-eep shearing or clipping machine, the combination, withrecessed frame 0, 0s

eillating' base-plate 0', supported thereby, the

universal joints and connections for the attachment of suitable means,and centers 01 d, 011 which said plate works, of a rocker-bar, a screw ffor impartinga rocking motion thereto, a screw-pin connecting therock-bar with the base-plate, a crank-pin and slide-bar for imparting anoscillating motion thereto, a

metal case or cover m, adapted to fit over and protect the working partsof the top portion of the machine, and screws n n for securing said caseor cover to the apparatus, substantially as set forth.

In Witness whereof I have hereunto set my CHARLES BURGON. Witnesses:
